Your editorial (13 September) accuses motor manufacturers of inaction on electric cars. This is based neither on evidence nor on understanding of the decades it takes to develop such technologies.

Industry is committed to a zero-emission future and is investing heavily in electrified and other technologies. But while it can deliver the technology, it can’t determine the pace of uptake. Increasing consumer confidence, addressing infrastructure accessibility and overcoming range anxiety are vital. As with any new technology, this is expensive, so long-term government support will be essential.

In the meantime, the industry is addressing emissions from conventionally powered vehicles. The latest petrol and diesel vehicles meet the world’s toughest emissions standards, helping to significantly reduce their impact on climate change and air quality, while providing affordable mobility to millions. Government has acknowledged the role these technologies will continue to play in the transition to zero-emission transport.

Consumers should have the confidence to choose the car now that best meets their driving needs – whatever the technology. It is, after all, fleet renewal that offers the fastest way to address environmental concerns.Mike HawesChief executive, Society of Motor Manufacturers and Traders

• Whatever the government decides on going electric, rationalising public charging is a priority now. As a recent electric car owner I’ve been amazed by how many different companies operate public charge points. They all have different payment methods, ranging from a monthly subscription (uneconomic if you are an occasional user) to card systems. Many are dependent on smartphone apps, thereby discriminating against drivers who don’t have a smartphone.

Only one company, Instavolt, has the obvious, which is pay as you go using a contactless debit card at the charge point. Why can’t all public charge points use this simple system?Zofia DymitrCombe St Nicholas, Somerset

• The scientific basis for the editorial claim that electric cars “emit no toxic filth” is unclear. Manufacturers claim zero tailpipe emissions. Studies suggest non-exhaust sources account for more than four-fifths of PM10 and PM2.5 emissions from traffic. Electric vehicles are heavier and produce particulates, from tyre and brake wear.Robin MorrisOxford
